Type
This indicator represents the type of data stream being transmitted by the external device. The external device
indicates type using specific bits in the channel status data. Typically PCM types are shown with green background
and non-PCM types, such as Dolby AC3, have a yellow background.
Valid linear PCM types (bit width):
PCM PCM16 PCM18
PCM19 PCM20 PCM22
PCM23 PCM24
Valid compressed, non-PCM types:
Dolby AC-3
MPEG1L1 MPEG1L2 MPEG2
MPEG2AAC MPEG2L1 MPEG2L2
MPEG2L3 MPEG-4
DTS I DTS II DTS III
ATRAC ATRAC2/3
Emphasis
Off (gray) Emphasis is off
50/15us (green) 50/15us pre-emphasis
J17 (green) CCITTJ.17 emphasis
Unknown (green) Emphasis not indicated
The emphasis bit is part of the channel status data and is used by a transmitter to indicate if the audio data being
transmitted has been encoded with audio signal emphasis.
Rate
This indicator represents sample rate encoded in the channel status data.
Valid Rates include the following:
32.0; 44.1; 48.0; 88.2; 96.0; 176.4; 192.0 kHz (all in green) or Unknown (red)
Note: it is the responsibility of the transmitting device to send rate status that matches the actual rate of the audio
data stream being sent. However, it is possible for a rate discrepancy to exist during a valid transmission.
Clock Rate
Clock Rate displays a real-time measurement of the sample rates of the incoming signals. These measurements are
very useful for evaluating and validating digital inputs when synchronization or clocking issues are encountered.
The Settings Menu offers a “High Resolution Clock Rate” option that provides three decimal places of accuracy
instead of the default one decimal place. With this option enabled, lower digits may fluctuate rapidly as a result of
measurement resolution.
When WideWire In is checked to enable AES dual-wire operation on input, Clock Rate should read half of the
encoded channel status rate described above. For example, when running at 192 kHz with dual-wire inputs, the
Clock Rate should indicate 96.0 kHz and the LR Clock should indicate 192 kHz.
